    • Crystal Growth Kinetics of Boron Oxide Under Pressure 

      Aziz, Michael; Nygren, Eric; Hays, James F.; Turnbull, David (American Institute of Physics, 1985)
      We have measured the crystal growth rate u of B2O3-I in the amorphous phase, as it varied over five orders of magnitude with changes in temperature and pressure. We eliminated the crystal nucleation barrier by seeding the ...

    • Enhancing the Efficiency of SnS Solar Cells bia Band-Offset Engineering with a Zinc Oxysulfide Buffer Layer 

      Sinsermsuksakul, Prasert; Hartman, Katy; Kim, Sang Bok; Sun, Leizhi; Park, Helen Hejin; Chakraborty, Rupak; Buonassisi, Tonio; Gordon, Roy Gerald (American Institute of Physics, 2013)
      SnS is a promising earth-abundant material for photovoltaic applications. Heterojuction solar cells were made by vapor deposition of p-type tin(II) sulfide, SnS, and n-type zinc oxysulfide, Zn(O,S), using a device structure ...

    • Which One? Grounding the Referent Based on Efficient Human-Robot Interaction 

      Ros, Raquel; Lemaignan, Severin; Sisbot, E. Akin; Alami, Rachid; Steinwender, Jasmin; Hamann, Katharina; Warneken, Felix (IEEE, 2010)
      In human-robot interaction, a robot must be prepared to handle possible ambiguities generated by a human partner. In this work we propose a set of strategies that allow a robot to identify the referent when the human partner ...
